Patented Mar. 9, 1920.

Application filed May 20; 1918. Serial No. 235,595. r

To aZZ whom it may concern: I

Be it known that I, LOIS E. JAnnnT'r, a citizen of the United States, residing at Asheville, in the county of Buncombe and State of North Carolina, have invented new and useful Improvements in Stovepipe- Thiinbles, of which the following is a specification.

This invention relates to improvements in stove pipe thimbles, the object of the invention being to provide an improved stove pipe thimble which embodies means for positively engaging and clamping the end of the stove pipe inserted in the thimble, so as to prevent the stove pipe from bemg pushed too farinwardly into the fine and to also prevent the stove pipe from becoming casually detached from the thimble.

With the above and other objects in view, the invention consists in the construction, combination and arrangement ofv devices hereinafter described and claimed.

In the accompanying drawings Figure 1 is a perspective view of a stove pipe thimble constructed and arranged in accordance with my invention. I

Fig. 2 1s a plan of a strip adapted to be I bent into the form of the thimble.-

Fig. is sectional view on the plane indicated by the line 3-3 of Fig. 1.

Fig. 4 is a similar view on the plane indicated by the line 4-4: of Fig. 1.

My improved stove pipe thimble is made of a strip 1 of sheet metal of suitable length and breadth. The metal sheet is bent to form a cylinder and is arranged with its ends in overlapping relation. Near one'end the thimble sheet is formed with adjusting tongues 2 which are cut out therefrom and near the opposite end the thimble sheet is formed with a series of appropriately spaced adjusting slots 3 which may be engaged by the tongues to lock and secure the ends of the thimble sheet together and form a thinnble of any desired diameter. The tongues after they have been placed'in the desired adjusting openings 3 are clenched on the inner side of the thimble as shown in Fig.3.

The thimble is also formed with stove pipe stopping and clamping tongues and 6 which are cut therefrom and bent iu-V wardly and which are preferably of an oblong rectangular form here shown. As will be seen, the tongue 4 is longer than the tongue 6 and said tongues extend inwardly at an incline. The ends of the tongues are ad acenteach other and are arranged to receive the end ofthe stovepipe between them.

These tongues owing to the material of whlch the thlmble 1s formed, are resilient and serve to engage and clamp the inner end of the stove pipe which is arranged in the thimble so that the said tongues not only serve to stop the stove pipe and prevent it from being forced into the flue but also securely clamp the inner end of the stove pipe between them and, while permitting it I to be withdrawn from I the thimble when desired, serve to prevent the pipe from be-- coming casually detached from the thimble.

As the stove pipe is pushed into the thimble itwill first engage the short tongues 6 and press the same outwardly and then the end of the stove pipe'will pass under the long tongues 4-. The tongues 4 will act as a stop to prevent furthen inward movement of the stove pipe and the end of the stove pipe will be gripped between the said tongues 4t and 6.

Preferably the front edge of the stove pipe thimbleis formed with an outwardly projecting lateral flange as at 5.

Having thus described the what is claimed as new is v i 1. A stove pipe thimble having its inner 7 wall provided with a pair of inwardly projecting inclined resilient tongues extending invention,

lengthwise of the thimble and having their ends adjacent each other and adapted to receive the ends of a stove pipe between them and grlp the same.

2. A stove pipe thimble having its inner wall provided with a pair of inwardly projecting inclined resilient tongues extending lengthwise of the thimble and having their ends adjacent each other and adapted to receive the end of a stove pipe between them and grip the same. one of said tongues being longer than the other.

In testimony whereof I afiix my signature.
